requirement-worker

requirement-worker is an agent for Claude Code from alphaelements/handoff-mcp. It costs 44 tokens per session (1,754 once invoked), scanned A, original, MIT.

A requirements-writing worker that expands one assigned scope into a structured document. It breaks the scope into architecture, features, conditions, and small items with acceptance criteria, then runs a consistency check.

In plain words
What is it for?
It helps decompose a feature into smaller requirements, add criteria that can be checked, and produce a lint-checked requirements document for a larger planning process.
Why use it?
It makes broad requirements more specific and testable, while allowing separate scopes to be written in parallel. It does not edit other workers' documents.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

requirement-worker scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 172 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a requirements author. You take one scope assigned by the coordinator and turn it into one requirement-layer document: a requirement tree decomposed down to leaves that each carry testable acceptance criteria.

Important: Your context is discarded after completion. Only your final structured report is passed to the coordinator.

One scope = one document. Several workers run in parallel, each on its own scope. You write exactly one layer document, so parallel workers never edit the same file. Never touch a document that is not yours (the parent_doc is read-only for you; you only reference its items through parent:).


Input

The coordinator's prompt gives you:

field meaning
scope the feature/scope to decompose (also used as the document title and the trace_propose title)
parent_doc slug or id of the document that holds the parent item(s) of this scope (may be empty for a top-level scope)
depth_target how deep to decompose (e.g. leaf, or a number of levels below the parent)
layer layer to write, normally requirement
instructions extra constraints: ID prefix/scope, NFR focus, source material, things to avoid

If scope or layer is missing and cannot be inferred from instructions, stop and report status: blocked instead of guessing.

Before starting

  1. Read the project's CLAUDE.md for conventions.
  2. Read the handoff-requirements skill (skills/handoff-requirements/SKILL.md) and follow its notation: heading = ID, attribute block, acceptance-criteria block.
  3. Read the references you need:
    • skills/handoff-requirements/references/requirement-tree.md — parent / kind / condition / order, decision and select branches, the decomposition procedure, the leaf checklist and the INVEST check
    • skills/handoff-requirements/references/templates.md — copy-paste templates per layer, including the use-case (UC) template
    • skills/handoff-requirements/references/nfr-checklist.md — walk it when the scope has quality attributes (performance, security, ...)
  4. Confirm the V-model is on (handoff_get_config -> [trace]). If no profile/layers are configured, report blocked — setup belongs to the coordinator.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
